Perhaps you should try some spelling variations:
thanh trung » thanh tung
hanh trung » hanh trang, manh trung, danh trung
trinh ban » trinh han, trinh san, trinh dan
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
ban cong » bang cong, van cong, phan cong
cong tac » cong ty
than sao » than so, than vao, thanh san
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((hanh trung) OR (thanh trung)) trinh ban cong tac ((than sao) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh trung) OR (thanh trung)) trinh ban cong tac ((than sao) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh trung) OR (thanh trung)) trinh ban cong tac ((than sao) or (toan cao))*.
